Which are the only courts in the federal system that can have jury trials?

US District Courts (trial courts) use juries as triers of fact. The Sixth Amendment guarantees the right to a trial by jury in criminal cases; however, the defendant also has the option of requesting a bench trial where the judge takes the place of the jury.

Appellate courts, such as the US Courts of Appeals Circuit Courts and the US Supreme Court, do not use juries because they are not triers of fact. Appellate courts only review cases to determine whether trials were conducted according to law and constitutional protections, in an attempt to ensure the party or parties in the case received a fair hearing.
